Police, who are treating the death as a homicide, would provide no further information about their investigation.

The block of well-kept homes and lawns just south of 126th St. on Troy's north side was quiet on Saturday morning. A woman at the Second Avenue address would not talk to a reporter.

David Somers, 37, of 447 Third Ave., said he passed the Second Avenue house Friday night on his bus ride home from work at a little after 11 p.m. He said he noticed a few teenagers in front of the home. By the time he got off the bus at the corner, dozens were in the road, crying and screaming, he said.

Walker lived in the Griswold Heights Apartment complex operated by Troy Housing Authority. Friends and family were gathered solemnly outside the residence on Saturday. At around 12:45, paramedics arrived in response to a 911 call about Eshane Walker's mother, who was taken to a hospital.

Ron Walker, Eshane's grandfather, said the family did not want to discuss his grandson's death or what distress his daughter experienced to require medical attention.

Young people who'd heard about Walker's fate on Saturday posted notes including the phrase "RIP Eshane" on the social media site Twitter. Many expressed grief. "you family is in my prayers," wrote someone using the name SchuylerAnne. "Idk how someone could stab someone at a party! It blows my mind!"
